Hello,

I made DB as date_and_time tag in Step7 

and I try to display the date_and_time on TP-1500. So, I use date/time field.

But it was not working.

Please let me have the solution I want to display step7 date_and_time tag on HMI.

Hello,

Do you want to synchronize date and time?

Perhaps this might help:

Time synchronization between WinCC and a SIMATIC PLC

Best regards,

Wizard

My quoetion is not sync . I will recod date and time to the DB when true a bit.

And I want to display the date and time in DB on HMI using PLC tag.

if DB[0]  2022.05.03.14.30 in the DB, hmi display the date and time.

I used date/time field and match plc tag but it is not working.

I use s300 or s400  and you can see my attached picture that db datatype is date and time 

Firstly, many thanks for your support.

PLC program is step7(simatic manager) and HMI is Tia-portal.

DB type is date and time.

I found what happen in here but I didn't understand.

Anyway, I made the db as array like date[0] .. [50]. in this case is displayed *********** 

So, I changed array to normal name like date_aaa and then it is working well.

array case is not working for my program.
